BUTTER-JAR.

SPECIFICATION forming part of Letters Patent No. 438,439, dated October 14, 1890.

Application filed February 1, 1890. Serial No. 338,860. (No model.)

To all whom it may concern:

Be it known that I, PERRIN F. LEWIS, a citizen of theUnited States, residing at Russell, in the county of Warren and State of Pennsylvania, have invented certain new and useful Improvements in Butter-Jars; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to certain new and useful improvements in but'terjars, and has for its object toprovide a jar composed of inner and outer cases secured by means of plaster-of-paris or other suitable cement.

A further object of the invention is to provide a fruit-jar that willnot be easily broken when in use.

To the above ends and to such others as the invention may pertain the same consists in the peculiar construction and in the novel combination, arrangement, and adaptation of parts, all as more fully hereinafter described, shown in the accompanying drawings, and then specifically defined in the appended claim.

The invention is clearly illustrated in the accompanying drawings, which, with the letters of reference marked thereon, form a part of this specification, like letters of reference indicating like parts throughout the several views, and in which drawings Figure 1 is a perspective view of a jar constructed in accordance with my invention with the top secured in place. Fig. 2 is a perspective view of the jar with the cover removed and a portion of the exterior case broken away, showing the inner case. Fig.

3 is a bottom plan view of the cover removed, showing the rubber packing.

Reference now being had to the details of the drawings by letter,A is the outer case or package, which may be of wood or metal, and serves to protect the inner case B, which may be of glass or metal adapted to that purpose. In the present case I have shown glass. The case B is made small enough to set inside of the case A and leave a space about half an inch wide on all sides between it and the outer case A. In this space 0, Iplace plasterof-paris or other suitable cement, so that the outer and inner cases are held firmly in position. The top of the inner case should come near enough to the top of the outer case tov form the shoulder 19, upon which the cover D rests. This cover is of ordinary and wellknown construction, and is provided around the under side of the rim with suitable rubber packing E, adapted to render the case airtight when the cover is placed in position and the lever F is placed in the ears G, as shown in Fig. 1.

I am aware that it is not new to close abutter-package and other receptacles by means of a lockin g-lever extending across the top of the same and engaging ears on the body of the receptacle and I am also aware that it is old to form an interior shoulder on which the cover rests, and do not seek to cover either of these constructions broadly, but restrict myself to my particular construction and arrangement of parts.

Having thus described my invention, what I claim to be new, and desire to secure by Letters Patent, is-

The combination,with a butter-jar consisting of an outer and an inner case with an intermediate layer of cement between them and a shoulder 1) within the jar near the top, of a cover fitting the jar, rectangular ears pivotally secured to the outer face of the jar, a cross-bar 0n the upper face of the cover, and a removable lever F, adapted to engage said ears and to rest upon said bar with its ends tapered and sprung into place, substantially as shown and described.

In testimony whereof I afiix mysignatu re in presence of two witnesses.

PERRIN F. LEWIS.
